Lipid-Lowering Medications for Managing Dyslipidemia: A Narrative Review.

Dyslipidemia refers to the change in the normal levels of one or more lipid components in the bloodstream, which include triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). Dyslipidemia represents a substantial source of danger for cardiovascular disease (CVD). Effectively managing dyslipidemia involves a thorough strategy that includes changing one's lifestyle and using medications that are specifically designed to target the complex processes involved in lipid metabolism. Lipid-lowering treatments play a crucial role in this approach, providing a wide range of medications that are developed to specifically target different components of dyslipidemia. Statins are the main drug among these medications. Other drugs that are used with statin or as monotherapy include fibrates, omega-3 fatty acids (OM3FAs), ezetimibe, bile acid sequestrants, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, and bempedoic acid. Using the PubMed database, we reviewed the literature about dyslipidemia, drugs used for treating dyslipidemia, their efficacy parameters, and common adverse events. We also reviewed the international guidelines for treating dyslipidemia and discussed the future of lipid-lowering medications. More trials and experiments are still required to verify the effectiveness of many lipid-lowering drugs and to know their common adverse events to be able to manage them properly.

Sodium-Glucose Cotransporter Inhibitors: Cellular Mechanisms Involved in the Lipid Metabolism and the Treatment of Chronic Kidney Disease Associated with Metabolic Syndrome.

Metabolic syndrome (MetS) is a multifactorial condition that significantly increases the risk of cardiovascular disease and chronic kidney disease (CKD). Recent studies have emphasized the role of lipid dysregulation in activating cellular mechanisms that contribute to CKD progression in the context of MetS. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have demonstrated efficacy in improving various components of MetS, including obesity, dyslipidemia, and insulin resistance. While SGLT2i have shown cardioprotective benefits, the underlying cellular mechanisms in MetS and CKD remain poorly studied. Therefore, this review aims to elucidate the cellular mechanisms by which SGLT2i modulate lipid metabolism and their impact on insulin resistance, mitochondrial dysfunction, oxidative stress, and CKD progression. We also explore the potential benefits of combining SGLT2i with other antidiabetic drugs. By examining the beneficial effects, molecular targets, and cytoprotective mechanisms of both natural and synthetic SGLT2i, this review provides a comprehensive understanding of their therapeutic potential in managing MetS-induced CKD. The information presented here highlights the significance of SGLT2i in addressing the complex interplay between metabolic dysregulation, lipid metabolism dysfunction, and renal impairment, offering clinicians and researchers a valuable resource for developing improved treatment strategies and personalized approaches for patients with MetS and CKD.

Overlapping Pattern of the Four Individual Components of Dyslipidemia in Adults: Analysis of Nationally Representative Data.

Background/Objectives: Dyslipidemia is a well-established risk factor for cardiovascular disease (CVD). However, among available drug treatments, only those targeted at lowering LDL-C and consequently TC have demonstrated efficacy in preventing CVD. This is to say that the benefit for those with isolated high TG or low HDL-C is limited. The objective of this study is to examine the overlapping pattern of the four dyslipidemia components in US adult populations, which is important for quantifying the proportion of those who are less likely to benefit from lipid-lowering drugs and for a more precise use of the drug. Methods: A total of 7822 participants aged over 20 with abnormalities in any of the four lipid parameters, excluding those on lipid-lowering medications, were included from the National Health and Nutrition Examination Survey (NHANES) cycles spanning 1999-2000 through 2017-2018. The proportions of different combinations of them were calculated and presented using area-proportional Euler plots. Results: High TC, high LDL-C, high TG, and low HDL-C were seen in 32.8% (95% CI: 31.3%-34.2%), 28.1% (95% CI: 26.6%-29.6%), 26.7% (95% CI: 25.4%-28.0%), and 65.9% (95% CI: 64.0%-67.7%) of the people with dyslipidemia, respectively. The proportions of dyslipidemia cases attributable to "high LDL-C or high TC" (irrespective of HDL-C and TG levels), "normal LDL-C, normal TC, but high TG" (irrespective of HDL-C level), and "normal LDL-C, normal TC, normal TG, but low HDL-C" (i.e., isolated low HDL-C) accounted for 37.5% (95% CI: 35.9%-39.1%), 18.3% (95% CI: 17.2%-19.4%), and 44.2% (95% CI: 42.5%-46.0%), respectively. Conclusions: Some two-thirds of those with dyslipidemia had low HDL-C or high TG but normal LDL-C and normal TC. As these people are less likely to benefit from currently available drug treatments in terms of CVD prevention, it is important to identify other effective strategies or interventions targeted at them in order to achieve more precise and cost-effective management of dyslipidemia.

The role of periodontitis in the development of atherosclerotic cardiovascular disease in participants with the components of metabolic syndrome: a systematic review and meta-analysis.

Prevention of atherosclerotic cardiovascular disease (ASCVD) is important in individuals with metabolic syndrome components (MetS), and periodontitis may play an important role in this process. This study aims to evaluate the association between periodontitis and ASCVD in participants with the components of MetS, including obesity, dysglycemia, hypertension, and dyslipidemia. This study conducted followed the MOOSE reporting guidelines and the PRISMA 2020 guidelines. EMBASE, MEDLINE, Web of Science, Cochrane Library, PubMed and OpenGrey were searched for observational studies about the linkage of periodontitis to ASCVD in people with MetS components up to April 9, 2023. Cohort, case-control and cross-sectional studies were included after study selection. Quality evaluation was carried out using the original and modified Newcastle-Ottawa Scale as appropriate. Random-effects model was employed for meta-analysis. Nineteen studies were finally included in the quality analysis, and all of them were assessed as moderate to high quality. Meta-analyses among fifteen studies revealed that the participants with periodontitis were more likely to develop ASCVD in those who have dysglycemia (RR = 1.25, 95% CI = 1.13-1.37; p < 0.05), obesity (RR = 1.13, 95% CI = 1.02-1.24; p < 0.05), dyslipidemia (RR = 1.36, 95% CI = 1.13-1.65; p < 0.05), or hypertension (1.20, 95% CI = 1.05-1.36; p < 0.05). Periodontitis promotes the development of ASCVD in participants with one MetS component (obesity, dysglycemia, hypertension or dyslipidemia). In people with MetS components, periodontitis may contribute to the ASCVD incidence.

Association between biomarkers of inflammation and dyslipidemia in drug resistant tuberculosis in Uganda

BackgroundActive tuberculosis (TB) significantly increases the risk of cardiovascular disease, but the underlying mechanisms remain unclear. This study aimed to investigate the association between inflammation biomarkers and dyslipidemia in patients with drug-resistant TB (DR-TB).MethodsThis was a secondary analysis of data from a cross-sectional multi-center study in Uganda conducted 2021. Participants underwent anthropometric measurements and laboratory tests included a lipid profile, full haemogram and serology for HIV infection. Dyslipidemia was defined as total cholesterol > 5.0 mmol/l and/or low-density lipoprotein cholesterol > 4.14 mmol/l, and/or triglycerides (TG) ≥ 1.7 mmol/l, and/or high density lipoprotein cholesterol (HDL-c) < 1.03 mmol/l for men and < 1.29 mmol/l for women. Biomarkers of inflammation were leukocyte, neutrophil, lymphocyte, monocyte, and platelet counts, as well as neutrophil/lymphocyte (NLR), platelet/lymphocyte, and lymphocyte/monocyte (LMR) ratios, mean corpuscular volume (MCV), and the systemic immune inflammation index (SII) (neutrophil × platelet/lymphocyte). Modified Poisson Regression analysis was used for determining the association of the biomarkers and dyslipidemia.ResultsOf 171 participants, 118 (69.0%) were co-infected with HIV. The prevalence of dyslipidemia was 70.2% (120/171) with low HDL-c (40.4%, 69/171) and hypertriglyceridemia (22.5%, 38/169) being the most common components. Patients with dyslipidemia had significantly higher lymphocyte (P = 0.008), monocyte (P < 0.001), and platelet counts (P = 0.014) in addition to a lower MCV (P < 0.001) than those without dyslipidemia. Further, patients with dyslipidemia had lower leucocyte (P < 0.001) and neutrophil (P = 0.001) counts, NLR (P = 0.008), LMR (P = 0.006), and SII (P = 0.049). The MCV was inversely associated with low HDL-C (adjusted prevalence ratio (aPR) = 0.97, 95% CI 0.94–0.99, P = 0.023) but was positively associated with hypertriglyceridemia (aPR = 1.04, 95% CI 1.00-1.08, P = 0.052).ConclusionsIndividuals with dyslipidemia exhibited elevated lymphocyte, monocyte, and platelet counts compared to those without. However, only MCV demonstrated an independent association with specific components of dyslipidemia. There is need for further scientific inquiry into the potential impact of dyslipidemia on red cell morphology and a pro-thrombotic state among patients with TB.

Relationship Between HDL and Urine pH in Patients with Urinary Tract Stones

Decreased HDL levels are one of diagnosis component of dyslipidemia which is part of the metabolic syndrome. when HDL levels decrease, its role as an anti-atherosclerotic can affect insulin resistance and it can eventually lower urine pH and potentially can cause urinary tract stones formation. The objective of this study is to determine the correlation between HDL Levels and Urine pH in Patients with Urinary Stones. A hospital based cross-sectional study included 52 patients with Urinary Stone who attended urology outpatient clinic in dr. M. Soewandhie General Hospital Surabaya during April-June 2022. HDL levels and Urine pH were recorded. The correlation between HDL levels and urine pH were tested using Spearman’s test. Mean of HDL levels were 44,96±9,109 mg/dL, and urine pH was 5,7692±0,70336. HDL levels was positively correlated with urine pH (r=0,336, p=0,015). There is a significant correlation between HDL levels and urine pH in patients with urinary stones. This is line with the fact that if HDL levels decrease, the urine pH will also decrease due to the influence of insulin resistance on the metabolic syndrome in patients with urinary tract stones.

Dyslipidemia and hyperuricemia: a cross-sectional study of residents in Wuhu, China

BackgroundWhile dyslipidemia has been recognized as a potential risk factor for hyperuricemia, there is currently a dearth of large-scale data specifically focused on studying the relationship between these two conditions. To address this gap, the present study analyzed a dataset of 298,891 physical examination records to investigate in greater detail the clinical classification and compositional relationship between hyperuricemia and dyslipidemia.MethodsFor this investigation, a cross-sectional research design was utilized to analyze physical examination data that was gathered from Yijishan Hospital in Wuhu, China between 2011 and 2016. Logistic regression was employed to examine the association between hyperuricemia and dyslipidemia. Furthermore, the association between hyperuricemia and dyslipidemia was evaluated based on the clinical classifications of dyslipidemia and its components.ResultsA total of 298,891 participants from China (124,886 [41.8%] females) were included in the study, with an age range of 18 to 90 years (mean [SD]: 47.76 [13.54] years). In multivariate analysis, the odds of hyperuricemia was 1.878 times higher in patients with dyslipidemia compared to those without dyslipidemia (95% confidence interval [CI]: 1.835–1.922). In the clinical classification of dyslipidemia, individuals with hypertriglyceridemia and mixed hyperlipidemia had 1.753 times (95% CI: 1.706–1.802) and 1.925 times (95% CI: 1.870–1.982) higher odds of hyperuricemia, respectively, compared to those without dyslipidemia. Among the components of dyslipidemia, the odds ratios for hyperuricemia in individuals in the fourth quartile compared to those in the first quartile were 3.744 (95% CI: 3.636–3.918) for triglycerides, 1.518 (95% CI: 1.471–1.565) for total cholesterol, and 1.775 (95% CI: 1.718 − 1.833) for non-high-density lipoprotein cholesterol.ConclusionsDyslipidemia has been independently linked with hyperuricemia. Moreover, the elevation of triglycerides or total cholesterol levels, including conditions such as hypertriglyceridemia and mixed hyperlipidemia, have been observed to have a positive association with the development of hyperuricemia.

A Holistic View of Psoriasis: Examining Its Association With Dyslipidemia and Obesity in a Decade-Long Systematic Review and Meta-Analysis.

Psoriasis is a multifaceted inflammatory condition with systemic implications, impacting not only the skin but also various organs and overall health. It is associated with mood disorders, malignancy, infections, and components of metabolic syndrome, including diabetes, atherogenic dyslipidemia, and obesity. The coexistence of psoriasis with obesity poses additional challenges, as obesity worsens psoriasis severity and reduces treatment effectiveness. This systematic review and meta-analysis aim to further understand the associations between psoriasis, dyslipidemia, and obesity. Our systematic review of six studies revealed significant links between psoriasis and both dyslipidemia and obesity. Individuals with psoriasis exhibited a 1.40-fold higher likelihood of dyslipidemia (odds ratio (OR) 1.40, 95% confidence interval (CI) 1.24-1.58) and a 1.37-fold higher likelihood of obesity (OR 1.37, 95% CI 1.23-1.53) compared to those without psoriasis. These findings emphasize the systemic nature of psoriasis and its implications for metabolic health. In conclusion, this review underscores the importance of holistic management for psoriasis patients. Further research is warranted to explore underlying mechanisms and develop targeted therapeutic strategies. These findings contribute valuable insights to promote the overall well-being of individuals with psoriasis.

The Modulatory Bioeffects of Pomegranate (Punica granatum L.) Polyphenols on Metabolic Disorders: Understanding Their Preventive Role against Metabolic Syndrome

Modern research achievements support the health-promoting effects of natural products and diets rich in polyphenols. Pomegranate (PG) (Punica granatum L.) contains a considerable number of bioactive compounds that exert a broad spectrum of beneficial biological activities, including antimicrobial, antidiabetic, antiobesity, and atheroprotective properties. In this context, the reviewed literature shows that PG intake might reduce insulin resistance, cytokine levels, redox gene expression, blood pressure elevation, vascular injuries, and lipoprotein oxidative modifications. The lipid parameter corrective capabilities of PG-ellagitannins have also been extensively reported to be significantly effective in reducing hyperlipidemia (TC, LDL-C, VLDL-C, and TAGs), while increasing plasma HDL-C concentrations and improving the TC/HDL-C and LDL-C/HDL-C ratios. The health benefits of pomegranate consumption seem to be acheived through the amelioration of adipose tissue endocrine function, fatty acid utilization, GLUT receptor expression, paraoxonase activity enhancement, and the modulation of PPAR and NF-κB. While the results from animal experiments are promising, human findings published in this field are inconsistent and are still limited in several aspects. The present review aims to discuss and provide a critical analysis of PG’s bioeffects on the components of metabolic syndrome, type-2 diabetes, obesity, and dyslipidemia, as well as on certain cardiovascular-related diseases. Additionally, a brief overview of the pharmacokinetic properties, safety, and bioavailability of PG-ellagitannins is included.

Prevalence and determinants of dyslipidemia among adults in the community: A cross-sectional study in a selected province, Sri Lanka

BackgroundDyslipidemia is an important modifiable risk factor for cardiovascular diseases (CVDs). The aim of the present study was to assess the prevalence and determinants of dyslipidemia among adults in a rural community in Sabaragamuwa province of Sri Lanka. MethodsA descriptive cross-sectional study was conducted among adults aged between 30 and 60 years. Participants were selected using a three staged random sampling method. The WHO STEPS wise approach was used to collect data. Chi-square tests, independent sample t-test and binary logistic regression were used to obtain prevalence and determinants for dyslipidemia. ResultsThere were 366 participants with a male to female ratio of 1:2.1. Mean age was 45.2 years (SD = 8.8). The prevalence of dyslipidemia was 64.2 % overall, with 39.9 %,29 %,37.7 %, and 21.3 % for high total cholesterol (TC), low high density lipoprotein cholesterol (HDL-C), high low density lipoprotein cholesterol (LDL-C), and high triglycerides respectively. Increasing age, physical inactivity, low fruit and/or vegetable consumption and higher BMI were significantly associated with dyslipidemia. ConclusionTwo in every three adults in the community have dyslipidemia. High LDL-C was the most prevalent component of dyslipidemia followed by low HDL-C. Multisectoral intervention strategies are needed considering the predictors identified to combat with high prevalence of dyslipidemia in this population.

Association between Rapid Eye Movement Obstructive Sleep Apnea and Metabolic Syndrome in a Japanese Population.

Objective Rapid eye movement (REM) obstructive sleep apnea (OSA) is characterized by apnea and hypopnea events due to airway collapse occurring predominantly or exclusively during REM sleep. OSA is a potential risk factor for metabolic dysfunction. However, the association between REM OSA and risk of adverse health outcomes remains unclear. The present study investigated the association between REM OSA and metabolic syndrome (MetS), including the MetS components of hypertension, dyslipidemia, and hyperglycemia, in the Japanese population. Methods In total, 836 Japanese patients with mild to moderate OSA were enrolled in this study. We compared the prevalence of MetS, including hypertension, dyslipidemia, and hyperglycemia, between REM OSA and non-REM OSA via univariate analyses of descriptive statistics and logistic regression analyses. Results The prevalence of hypertension was 68.3% in the REM OSA group and 56.6% in the non-REM OSA group (p<0.05). In addition, the prevalence of metabolic syndrome was significantly higher (37.0%) in the REM OSA group than in the non-REM-OSA group (25.2%). Logistic regression analyses showed that the prevalence of hypertension and Mets was significantly greater in the REM OSA group than in the non-REM-OSA group. Conclusion Our findings suggest that patients with REM OSA, regardless of age, sex, and body mass index, are at a higher risk of developing hypertension and MetS than patients with non-REM OSA.

Dyslipidemia and SARS-CoV-2 spike antibody titres after the second and third doses of the BNT162b2 vaccine among healthcare workers in Japan.

This study aimed to examine the sex-associated differences in the relationship between dyslipidemia and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike immunoglobulin (Ig)G antibodies among BNT162b2 vaccine recipients. Participants were staff members (aged 21-75years) of a medical and research institution who underwent an anti-SARS-CoV-2 spike IgG antibody test after the second (n=1872) and third doses (n=1075) of the BNT162b2 vaccine. Dyslipidemia was defined as triglyceride level ≥150mg/dl, high-density lipoprotein-cholesterol level <40mg/dl, low-density lipoprotein-cholesterol level ≥140mg/dl, or lipid-lowering medication use. Multivariable linear regression was used to calculate the ratio of means for SARS-CoV-2 spike IgG titre according to dyslipidemia status. The prevalence of dyslipidemia was 38.0% in men and 19.6% in women. The relationship between dyslipidemia and SARS-CoV-2 spike IgG titres after the second dose differed markedly by sex (P for interaction <0.001). In men, dyslipidemia was associated with significantly lower IgG titres: the ratio of means (95% confidence interval) was 0.82 (0.72-0.93). However, this association disappeared after the third dose (0.96 [0.78-1.18]). Of the dyslipidemia components, hypertriglyceridemia was inversely associated with SARS-CoV-2 spike IgG antibody titre after both the second and third doses (ratio of means: 0.82 [0.70-0.95] and 0.73 [0.56-0.95], respectively). In women, IgG titres did not differ according to dyslipidemia or hypertriglyceridemia status after either dose. These results suggest a detrimental role of hypertriglyceridemia in the humoral immune response to the BNT162b2 vaccine for COVID-19 in men but not in women.

The relationship between uric acid and dyslipidemia in type 2 diabetic patients with urolithiasis

Background and objective: Diabetes mellitus (DM) is characterized by insulin resistance which canincrease the risk of kidney stone formation. This study aimed to find out the association between serum levels of uric acid and lipid profile in DM patients with urolithiasis in comparison to those without. Methods: This cross-sectional study was conducted at P K Das institute of medical sciences,Vaniamkulam, Palakkad, Kerala, India with the approval of the institutional ethical review committee for human studies. A total of 60 patients were included in the study.Group A patients with DM and urolithiasis, and group B patients with DM but without urolithiasis. Biochemical parameters studied were glucose, urea, creatinine, uric acid, creatinine, serum uric acid to creatinine ratio, lipid profile, HbA1c, and triglyceride glucose index. Statistical analysis was done using SPSS version 21. Results: We found a significant increase in uric acid, urea, serum uric acid to creatinine ratio, and triglyceride glucose index levels in diabetic urolithiasis cases as compared to diabetes mellitus cases without urolithiasis. We also found that total cholesterol, triglycerides, LDL-C, and VLDL-C levels were significantly increased, and HDL-cholesterol was significantly decreased in diabetic urolithiasis cases. Serum uric acid was positively correlated with total cholesterol, triglycerides, LDL-C, and VLDL-C and negatively correlated with HDL-C in diabetic urolithiasis cases. Conclusions: From this study, it is demonstrated that patients with diabetic urolithiasis are having high insulin resistance, altered lipoprotein metabolism, and increased level of serum uric acid. The dyslipidemia components are strongly associated with increased uric acid.

Association between dyslipidaemia and the risk of hyperuricaemia: a six-year longitudinal cohort study of elderly individuals in China

Background Despite abundant evidence linking dyslipidaemia to an increased risk of hyperuricaemia, the exact association between each component of dyslipidaemia and hyperuricaemia remains controversial. Thus, the objective of this research was to examine the correlation between dyslipidaemia and its components, as well as hyperuricaemia in Chinese people over the age of 60. Methods In this study, 4018 participants over 60 years without hyperuricaemia were investigated from 2014 to 2020. The association between each dyslipidaemia component and hyperuricaemia was evaluated employing Cox proportional hazards models. This research conducted further stratified and sensitivity analyses to assess the potential relationship. Results A total of 1155 participants suffered from hyperuricaemia (28.75%) at the time of the 6-year follow-up survey. In multivariable-adjusted analyses, compared to participants with normal lipid levels, those with dyslipidaemia had 1.28 times the risk (95% confidence interval 1.12 to 1.47) of experiencing hyperuricaemia. The hazard ratios (HR) (95% CI) comparing high TC, high TG, high LDL-C, and low HDL-C of dyslipidaemia with the regular group were 0.99 (0.72 to 1.37), 1.30 (1.07 to 1.57), 1.02 (0.70 to 1.50), and 1.20 (1.00 to 1.44), respectively. There was a nonlinear dose-response between TG, HDL-C, and serum uric acid (SUA). Conclusions Dyslipidaemia and its two distinct types, high TG and low HDL-C, increased hyperuricaemia incidence in this prospective cohort. Further research should be undertaken to investigate the possible reverse causality between different components of dyslipidaemia and hyperuricaemia.

Comparative Study on the Effect of Vidangadya Churna and Lekhana Basti in Medodushti with Special Reference to Dyslipidaemia

Introduction- Cardiovascular diseases (CVD) are the major cause of morbidity and mortality in our society in which Dyslipidaemia contributes significantly through atherosclerosis. All components of Dyslipidaemia get the most attention because of the link between plasma lipids &amp; CVD, as it is major risk factor for fatal diseases such as coronary artery disease (CAD). Sign &amp; symptomsof Medodushtidescribed in Ayurvedashows strikingly resemblance with Dyslipidaemia explained in modern medicine. Thus, while treating the Medodushti, selection of Dravya should have criteria that help inLekhana of excessive Meda-Kapha without Vayu-Prakopa&amp; normalising the Agni both at the level of Jatharagni&amp;Dhatwagni.&#x0D; Aims and objectives- Present study was undertakento assess the efficacy of Lekhana Basti&amp;VidangadyaChurna in the management of dyslipidemia.&#x0D; Material and methods-This study was carried out on 30 clinically diagnosed &amp; investigated individuals of Dyslipidaemia.

Obesity diabetes and dyslipidemia as determinants of immune checkpoint inhibitors response in non-small cell lung cancer.

e21104 Background: Immune checkpoint inhibitors (ICI) are standard of care in the treatment of non-small cell lung cancer (NSCLC). Predictive markers of response to ICI are being studied extensively. Obesity has been correlated with a better response to ICI in NSCLC and other types of cancer. This may in-part be related to high circulating leptin or impaired T-cell fatty acid oxidation within the tumor microenvironment. We aim to further explore the effects of obesity, dyslipidemia and other components of the metabolic syndrome such as diabetes on treatment outcomes on NSCLC patients receiving ICI. Methods: We conducted a retrospective cohort study in patients with NSCLC treated with pembrolizumab, nivolumab, durvalumab, cemiplimab or atezolizumab as monotherapy or combined with chemotherapy at Mount Auburn and Lahey Hospital between January 2016 to June 2021. Obesity was defined as body mass index (BMI) &gt; 30 kg/m2, dyslipidemia and type 2 diabetes were defined by ICD-10 diagnosis codes. Overall survival was evaluated. Kaplan-Meier survival analysis and cox proportional hazards regression were used to assess correlation between overall survival and obesity, dyslipidemia, type 2 diabetes, metformin use and statin use. These were adjusted for age, biological sex, cancer stage, ECOG and smoking status. Patients with BMI &lt; 18.5 were excluded. Results: We identified 408 patients with NSCLC who were treated with ICIs. Of these, 66.7% had adenocarcinoma, 29.1% had squamous and 4.2% had either adenosquamous, large cell or poorly differentiated carcinoma. Among these patients 23.3% were classified as obese, 55.6% had dyslipidemia and 23% had type 2 diabetes. Of these, 66% of patients received ICIs as monotherapy. Median survival was 840 days in obese patients compared to 483 days in non-obese patients (HR 0.66, CI 0.42-0.92, p = 0.014). Conversely, within this cohort, median survival in patients with dyslipidemia was 483 days when compared to 762 days in controls (HR 1.37, CI 1.07-1.81, p = 0.013). Overall survival was not significantly different between type 2 diabetes, metformin use or statin use. Conclusions: Our study shows a trend towards a better survival in obesity and poor survival associated with dyslipidemia. Obesity and dyslipidemia may be important markers of ICI response in patients with NSCLC regardless of treatment strategies. Further studies are needed to explore the molecular mediators within the metabolic syndrome that may provide a synergistic effect with immune checkpoint inhibitors.

The dose-response relationship of serum uric acid with Dyslipidaemia and its components: a cross-sectional study of a Chinese multi-ethnic cohort

BackgroundThe association between serum uric acid (SUA) and the components of dyslipidaemia and their dose-response relationships have not been thoroughly explored. This study assessed the relationship between SUA and each dyslipidaemia component in Dong, Miao, and Bouyei populations in Guizhou by sex and ethnicities and investigated the dose-response relationship.MethodsIn total, 16,092 participants aged 30–79 years from The China Multi-Ethnic Cohort (CMEC) Study were examined. Multivariable logistic regression models were applied to explore the relationship between SUA and each dyslipidaemia component by sex and three ethnicities. The dose-response associations between SUA and various dyslipidaemias were investigated using restricted cubic spline regression.ResultsAfter controlling for confounding factors, the SUA level in total participants positively correlated with each dyslipidaemia component, and women had higher odds ratios (ORs) for each dyslipidaemia component than men (P for trend < 0.001). At the SUA level > 6.37 mg/dL, ORs (95% CI) for dyslipidaemia in the Dong, Miao and Bouyei were 2.89 (2.00–4.19), 2.43 (1.70–3.48), and 3.26 (2.23–4.78), respectively. When the SUA concentration increased by 1 mg/dL, the ORs (95% CI) for total dyslipidaemia was 1.31 (1.24–1.37). A positive dose-response but nonlinear association was found between SUA and total dyslipidaemia, high total cholesterol, and low HDL, whereas an inverse U-shaped association was found between SUA and high LDL-C ( P-nonlinear< 0.0001).ConclusionThe SUA level was positively correlated with each dyslipidaemia component in Dong, Miao, and Bouyei adults, and sex and ethnic differences were also found. A nonlinear dose-response relationship was found between SUA levels and dyslipidaemia and its components. Further research is warranted to investigate the causal link between SUA levels and dyslipidaemia incidence.

Relationship between vigorous physical activity and health care costs among adolescents: ABCD Growth Study

BackgroundThe relationship between physical activity and health care costs among adolescents is not yet clear in the literature.ObjectiveTo analyze the relationship between physical activity and annual health care costs among adolescents.MethodsThe present sample was composed of 85 adolescents of both sexes with ages ranging from 11 to 18 years (mean age 15.6 ± 2.1). Health care costs were self-reported every month for 12 months, and information on health care values was verified with local pharmacies, private health care plans, and the National Health Service. The time spent in different physical activity intensities was objectively measured by accelerometers. Confounding variables were: sex, age, somatic maturation, body fatness, blood pressure, and components of dyslipidemia and insulin resistance. Multivariate models were generated using generalized linear models with gamma distribution and a log-link function.ResultsThe overall annual health care cost was US$ 733.60/ R$ 2,342.38 (medication: US$ 400.46 / R$ 1,278.66; primary and secondary care: US$ 333.14 / R$ 1,063.70). The time spent in vigorous physical activity (minutes/day) was negatively related to health care costs (r = -0.342 [95% CI: -0.537,—0.139]; β = -0.06 cents (95% CI: -0.089, -0.031).ConclusionVigorous physical activity seems to be associated with lower health care costs among adolescents.

Cardiometabolic factors and risk of non-arteritic anterior ischemic optic neuropathy: a systematic review and meta-analysis.

The purpose of this systematic review and meta-analysis of the literature is to evaluate the association between cardiometabolic risk factors (hypertension, diabetes mellitus, hypercholesterolemia/dyslipidemia, HDL cholesterol, LDL cholesterol, lipoprotein(a), and triglycerides) and non-arteritic anterior ischemic optic neuropathy (NAION). Pertinent publications were identified through a systematic search in PubMed and EMBASE databases, without language restrictions. The pooled odds ratios (OR) and standardized mean differences (SMD), with their 95% confidence intervals (95% CI) were estimated using random effects (DerSimonian Laird) models, as appropriate. A set of subgroup analyses and meta-regression analysis models were performed. Twenty-one studies (including 1560 patients with NAION and 2292 controls), examining the association between NAION and cardiometabolic risk factors, were eligible for the systematic review and meta-analysis. Hypertension (pooled OR = 1.50; 95% CI: 1.16-1.94), diabetes mellitus (pooled OR = 1.71; 95% CI: 1.33-2.21), and hypercholesterolemia/dyslipidemia (pooled OR = 2.00; 95% CI: 1.53-2.62) were associated with NAION. Among the components of dyslipidemia, higher serum triglycerides were associated with NAION, with a medium effect size (SMD = + 0.58, 95% CI: + 0.12 to + 1.04), whereas synthesis of four studies reporting on HDL and LDL cholesterol did not reveal any significant associations. A significant association between NAION and higher serum lipoprotein(a) levels (pooled OR = 2.88; 95%CI: 1.01-8.21) was also noted. This systematic review and meta-analysis found that NAION was associated with cardiometabolic factors, suggesting that vascular dysfunction may be implicated in the pathogenesis of the disease. Our findings may alert health care providers to try modifying these risk factors for NAION prevention.

Emerging advances in the pharmacologic treatment of nonalcoholic steatohepatitis and related cirrhosis.

The prevalence of nonalcoholic fatty liver disease (NAFLD) is rapidly growing throughout the world. Nonalcoholic steatohepatitis (NASH), the progressive form of NAFLD, is likely to become the leading cause of cirrhosis and etiology for liver transplantation in future decades in the Western World. Most patients with NAFLD have some components of metabolic syndrome, including obesity, insulin resistance, dyslipidemia, and hypertension. NAFLD encompasses a wide spectrum of liver damage, ranging from simple steatosis to NASH, that can progress to advanced liver disease, as well as hepatocellular carcinoma. Unfortunately, the options for the pharmacological treatment of NASH are still very limited. Nonetheless, several classes of therapies have shown promise, and are currently being evaluated in large phase 2b and phase 3 trials, creating some hope that selected agents will be approved in the coming years. As NASH is a heterogeneous disease, multiple mechanistic pathways are being targeted to achieve optimal treatment response. Combination therapy is also on the horizon, where 2 or more drugs targeting different mechanistic pathways are being used to boost the clinical response. In this review, we first present the current concept of the pathophysiology of NASH, focusing on the pathways currently targeted in clinical trials. We then present the pharmacological agents that are being evaluated in phase IIb of clinical development and beyond, using histological outcomes, and finally we present preliminary results from the combination trials that have already been initiated.
